The WDM market is enjoying a continual growth wave, rising 10 percent year-over-year in the second quarter of 2014 to $2.6 billion as more service providers deploy 100G in long-haul network applications.
During the second quarter, DWDM long-haul equipment revenue grew 18 percent year-over-year, while WDM metro equipment revenue grew 4 percent year-over-year, according to Dell'Oro Group.
"The recent second-quarter growth of 10 percent marked the eighteenth consecutive quarter that the WDM market has increased," said Jimmy Yu, vice president of Optical Transport research at Dell'Oro Group. "Furthermore, as an indication of the market's strength, twelve of those eighteen quarters grew at double-digit percentage rates."
Yu added that the WDM market isn't showing any signs of slowing. "A number of factors are driving the strong growth of WDM; the most significant of which is the global adoption and penetration of 100 Gbps wavelengths in long haul applications," Yu said.
Evidence of this trend is taking place at some of the largest traditional telcos and competitive providers. Telefonica and XO Communications both announced major 100G long-haul and metro upgrades with their suppliers Alcatel-Lucent and Infinera, for example.
